Nearly half of cities and towns across Japan are concerned about how to provide appropriate treatment to foreign workers as they prepare for an influx after this spring with the government's new policy on addressing a chronic labor shortage, a survey conducted by Kyodo News showed on Sunday.

But the survey, covering all of Japan's more than 1,700 municipalities, also found 47 percent of them are in favor of having more workers from abroad, as many companies continue to struggle with insufficient workforces amid the country's aging population and falling birthrate, japantoday.com reported.

Japan will introduce a new visa system in April as part of efforts to attract more foreign workers for the country's labor-hungry sectors, including nursing care, construction, farming and restaurant businesses.

Of the municipalities surveyed, 12 percent said they are concerned about whether they can ensure that employers treat foreign workers properly, such as providing necessary livelihood support and salaries on a par with their Japanese colleagues, and 35 percent said they generally think so too.

Combining the two figures, 47 percent of them are worried about how to coexist with foreign workers, with some citing the government's lack of specific measures as a major reason for their anxieties.

Among other opinions, the city of Odate in Akita Prefecture said that "many companies have no know-how about accepting foreigners" and called for support from the central and local governments.

Some of the municipalities that are not so positive about accepting more workers from other countries said they think higher priority should be given to efforts to secure jobs for elderly Japanese people and women.

The nationwide survey was conducted between November and January. It covered all of Japan's 1,788 municipalities, of which 99 percent or 1,768 responded.

Under the new visa system, Japan plans to accept up to around 345,000 foreign workers over the next five years.

They are mainly expected to come from nine Asian countries, including China, Indonesia, the Philippines and Vietnam.

With the policy to grant new visa statuses, Japan will formally open its doors to foreign blue-collar workers for the first time. In the past, the country has granted working visas only to people with high skills and professional knowledge such as doctors, lawyers and teachers.
